Product Code:SAE AMS4189
Title:Aluminum Alloy Welding Wire, 4.1Si -0.20 Mg (4643)
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope:This specification covers an aluminum alloy in the form of welding wire.This wire has been used typically as filler metal for gas-metal-arc or gas-tungsten-arc welding of heavy sections of aluminum alloys of similar composition to produce joints having inherently low dilution ratio of base-metal to weld-metal, and where the weldment may require solution and/or precipitation heat treatment, but usage is not limited to such applications.

Title:Surface Treatment of Polytetrafluoroethylene (PTFE), Preparation for Bonding
Issuing Committee:Ams P Polymeric Materials Committee
Scope:This specification covers the engineering requirements for preparing surfaces of polytetrafluoroethylene (PTFE) for bonding and the properties resulting from the treatment.This process has been used typically for rendering surfaces of parts capable of supporting a high strength adhesive bond. The bonding preparation can affect the electrical properties of the PTFE and this should be considered before using it for treatment of electronic components.
